This Yoga Mat Sling is made out of nothing but braided paracord! As such, it is durable, has no extraneous parts to break or wear out, and will fit almost any thickness of yoga mat. It's also durable while still being soft on both the skin and the mat. It is also machine washable, and with proper care will likely outlast your mat! I have many, many different colors of paracord, so if you want one in different colors just email me and we can talk about it. Even if I don't have a color you really want, give me a few extra days and I can get it for you.
